The mental ramifications of the injuries might have been more detrimental to Boyd than the physical issues.
"If you're not 100% focused on the hitter, and there's some percentage before you release the ball that's focused on something else, there needs to be regrouping," Boyd said. "Understanding why that hesitation is there. Understanding why you're not fully attacking. There were times last year where that probably was the circumstance."
His lack of focus is a reminder of his human nature; a hamstring injury, for example, can distract from the task in the batter's box.
Sometimes, the motions of his body preoccupied him. Other times he was overthinking his pitch selection. Either way, his game suffered.
